RCRA FACILITY INVESTIGATION

The RCRA Facility Investigation (RFI) is being conducted to characterize the environmental setting of CSSA, define the sources of contamination, define the degree and extent of contamination, identify actual or potential receptors, and assess whether any additional interim/stabilization measures (I/SM) may be warranted. The discussions below include only the tasks related to Facility Investigations and Treatability Studies. Discussion of other RFI subtasks will be included in future reports if changes or additions to previously reported activities occur. The majority of current ongoing environmental activities at CSSA are part of the RFI task. Work on each of these tasks is described in the following paragraphs. The main areas of work during this period included:

• Groundwater monitoring of on- and off-post wells;

• Groundwater monitoring of Westbay®-equipped wells;

• Verification and validation of analytical data;

• SVE system O&M at AOC-65;

• Continuation of bioreactor operation at SWMU B-3;

• Investigations of SWMU B-71, AOC-63, AOC-64 (Weston) and SWMU I-1, SWMU B-2, SWMU B-8, SWMU B-20/21, SWMU B-24, AOC-67, AOC-68, AOC-69, and AOC-73 (Parsons); and

• TCEQ approval of delisting the Coal Bins AOC and B-14, and closure of SWMU B-29.

RFI Work Plan

The Order requires the RFI WP task to include a Project Management Plan, Data Collection Quality Assurance Plan, Health and Safety Plan, and a Community Relations Plan. As previously agreed by USEPA, because the CSSA Environmental Encyclopedia includes all information required by the Order, it is used to fulfill this requirement. The RFI WP task makes up approximately 5 percent of the RFI phase. Estimation of percent complete is difficult due to the continuing need for plan addenda as new projects are identified and awarded. As of the end of Period 32, WPs currently under scope are 100 percent complete. The CSSA Environmental Encyclopedia will continue to be updated as WPs for any new projects are finalized. During Period 32, the Ecological Risk Assessment Work Plan for the North Pasture was completed, and the work plan for upcoming work at SWMU B-71 and AOC-64 was initiated.

Environmental Encyclopedia Updates

The CSSA website (www.stanley.army.mil) was updated with documents added to the Environmental Encyclopedia through the end of June 2008. The website includes CSSA’s Administrative Record as required under the Order. The electronic encyclopedia and hard copy encyclopedia were updated with all final reports through June 2008. Updates made in Period 32 included the following:

• Period 31 USEPA Progress Report;



• Fact Sheet No. 27;

• Final September 2007 On-Post Groundwater Monitoring Report;

• Final September 2007 Off-post Groundwater Monitoring Report

• Final June 2007 On-post Groundwater Monitoring Report;

• Final June 2007 Off-post Groundwater Monitoring Report;

• Final March 2007 On-post Groundwater Monitoring Report;

• Final March 2007 Off-post Groundwater Monitoring Report;

• Final DY02 Health and Safety Plan, May 2008;

• Final Ecological Risk Assessment Work Plan for North Pasture;

• Various correspondence to and from CSSA;

• Various meeting minutes; and

• Various tables of contents, site chronologies, and indices.

In an effort to improve the usability of the Environmental Encyclopedia, CSSA developed the online, interactive CSSA Environmental Summary (Site Management Plan). This summary operates along side the encyclopedia and gives a brief overview of past efforts, current status and planned actions. This summary includes active links to the encyclopedia and other appropriate web sources and will be periodically updated as work progresses. The CSSA Environmental Summary is available through password-protected access on the Environmental Encyclopedia home web page (www.stanley.army.mil).

Facility Investigations

An investigation of the facility is being conducted to:

• Characterize the environmental setting of the facility;

• Define the source(s) of contamination;

• Define the nature and extent of contamination; and

• Identify actual or potential receptors.

In some cases, multiple investigational phases may be necessary. Investigation results will be used to develop and evaluate alternatives during the Corrective Measures Study. All investigation activities are being conducted in accordance with the RFI WP discussed above.

Completion of the facility investigations for the planned RFI tasks is partially funded. Attachment 2 indicates the sites for which investigations have been initiated with site status as well as sites that have been identified, but not yet investigated. The Facility Investigations subtask makes up approximately 40 percent of the RFI phase. As of the end of Period 32, this task is approximately 75 percent complete.



A total of 84 SWMUs, AOCs, and Range Management Units have been identified at CSSA, and investigations have been conducted at 69 of those sites. A summary of the status of each site, including whether the site is recommended for closure or if closure is approved, is provided in Attachment 2. To date, Risk Reduction Standard 1 closure of 36 CSSA sites has been approved by Texas Commission on Environmental Quality (TCEQ), and ten sites were either delisted or granted No Further Action status.

SWMU and AOC Investigations

The Facility Investigation subtask makes up approximately 40 percent of the RFI phase. As of the end of Period 32, this task is approximately 75 percent complete.

SWMU B-71, AOC-63, and AOC-64

Site investigations at SWMU B-71, AOC-63, and AOC-64 are funded under United States Army Corps of Engineers (USACE) Contract No. DACA56-04-D-2006, task order (TO) No. DY01-Weston. Initial soil sampling/analyses at this site identified low levels of benzene. An Affected Property Assessment Report (APAR) for AOC-63 is being prepared. The APAR documents chemical of concern (COC) delineation activities and site-specific protective concentration level (PCL) development. Based on the assessment, no threat to human health or the environment is presented by COC concentrations at AOC-63 and no further investigation or corrective action is recommended for the site. The final APAR is planned for submittal in July 2008. Interim removal actions will be conducted at AOC-64 and SWMU B-71 in the next period to address munitions debris and affected soil.

SWMU I-1

A Release Investigation Report (RIR) is being prepared to request no further action status from TCEQ. The RIR will be submitted to TCEQ and USEPA in Period 33.

AOC-67 and AOC-68

Excavation activities were conducted at AOC-67 and AOC-68 on December 4, 2007. Approximately 50 cubic yards of soil and wheelabrator waste from each site was placed into three rolloff containers near the sites. Waste characterization and confirmation samples were collected on December 6, 2007. Waste characterization samples indicated the material met Class 2 Non-hazardous criteria and the investigation derived waste was disposed of off-post at Waste Management’s Covel Gardens landfill facility.

After soil removal, nine confirmation samples were collected at AOC-67 and submitted to Agriculture & Priority Pollutants Laboratories, Inc. (APPL) for lead analysis and six samples were collected at AOC-68 and submitted for volatile organic compounds (VOC), semi-volatile organic compounds (SVOC), and metals analysis on December 6, 2007. Results indicated that there remains some impacted soil material on the western side of AOC-68 and the bottom ditch area of AOC-67 and AOC-68. An additional sampling event was conducted on April 10, 2008 to determine the vertical extent of COCs in bottom samples at AOC-67/68. Results of analysis indicate that additional removal action on the western side of AOC-68 is necessary.



AOC-69

Ten soil samples were collected from AOC-69 and analyzed for VOCs, explosives, and CSSA metals. The surface of the site was also inspected for evidence of munitions debris, and none was found. Soil samples indicated concentrations above background/Tier 1 residential PCLs for lead at three locations. Additional soil samples were collected to delineate the extent of contamination. Due to the small amount of soil present at the site, it is anticipated that a small interim removal action will be conducted.

AOC–73

Work at SWMU B-73 included removal of debris, trash, and soil. On March 3, 2008, after removal was complete, ten samples were collected and submitted to APPL for the nine CSSA-analyzed metals, SVOCs, and VOC analysis. Additionally, one waste characterization sample was collected and submitted for toxicity characteristic leaching procedure metal analysis and total petroleum hydrocarbons from approximately 120 cubic yards of trash and soil media for disposal. Results of analysis indicated that no contaminants exist in the remaining soil media at AOC-73. Waste and soil media identified for disposal met Class 2 non-hazardous criteria and were removed to Waste Management’s Covel Gardens landfill facility. An RIR will be prepared for AOC-73 during Period 33.

SWMU B-2, B-8, B-20/21 & B-24

Removal actions were initiated at SWMU B-2 and SWMU B-8 to remove impacted soil media previously identified above Texas Risk Reduction Program (TRRP) Residential PCLs. Additionally, investigation of an eastern area of SWMU B-24 for a suspected disposal trench was accomplished during March 3, 2008 through March 7, 2008. Approximately 60 cubic yards of soil media from SWMU B-2 were removed and disposed of as Class 2 non-hazardous media at Covel Gardens landfill facility. Confirmation samples from SWMU B-2 were collected March 5, 2008. Results of analysis indicate that no remaining soil media are above TRRP residential PCLs.

Approximately 2,500 cubic yards of barium, copper, lead, and zinc impacted soil media were excavated from SWMU B-8 during March 10 through March 14, 2008. Approximately 1,000 cubic yards of impacted media within SWMU B-8 met RCRA hazardous criteria for lead of which 200 cubic yards also exceeded hazardous criteria for barium.

Approximately 600 cubic yards were stabilized with phosphate-induced metal stabilization material resulting in a Class 1 non-hazardous media. A letter of intent to move the non-hazardous lead impacted media to CSSA’s active firing range berm was sent to the TCEQ on April 24, 2008. TCEQ acknowledged the intent for movement of the impacted media by letter dated May 9, 2008. Removal of approximately 2,100 cubic yards of non-hazardous lead impacted media was initiated May 12, 2008 and was completed on May 22, 2008. Approximately 400 cubic yards of lead and barium impacted soil media remain at SWMU B-8 for future treatment and placement on the east pasture firing range berm. Confirmatory samples from the removal area at SWMU B-8 were collected on June 23, 2008 and analyzed for metals. Results will be used in the completion of a combined APAR for the North Pasture SWMUs.



Investigation of the eastern area of SWMU B-24 for an additional trench was conducted during the week of March 3 through March 7, 2008. Investigation included screening for potential unexploded ordnance (UXO) followed by excavation of the suspected area. Results of the investigation concluded that the area has no visible waste and is not a disposal trench. Fourteen samples for CSSA nine metals, SVOC, and VOCs were collected in the SWMU B-24 area (including the suspected eastern trench area) to define the lateral extent of the unit and identify any areas exceeding TRRP residential PCLs on June 25, 2008. Results of these analyses will be reviewed to determine if additional removal actions are warranted. An APAR will be submitted summarizing the investigation results.

To define the lateral extent and identify any areas exceeding TRRP residential PCLs, eleven samples from SWMU B-20/21 were collected on June 23, 2008 and analyzed for the nine CSSA metals. Results of these analyses will be reviewed and a determination made if additional removal actions are warranted. A draft APAR is scheduled for completion during Period 33.

Groundwater Investigation

The groundwater investigation subtask makes up approximately 15 percent of the RFI phase. As of the end of Period 32, this task is approximately 81 percent complete.

On- and off-post groundwater monitoring was conducted in accordance with the regulator-approved DQOs during Period 32. Sampling frequencies for on-post wells are determined by the long term monitoring optimization (LTMO) study completed in May 2005, as approved by TCEQ and USEPA. Based on the LTMO recommendations, on-post wells are sampled either quarterly, semi-annually, or biennially (every two years). Off-post wells are not included in the LTMO recommendations and are sampled quarterly under the DQOs and the CSSA Off-Post Monitoring and Response Plan. A map of the well locations is provided in Attachment 1 of this report.

The analyte list for each monitoring event was in accordance with the applicable WPs and DQOs. On- and off-post monitoring wells and Westbay-equipped wells were sampled for the SW-846 Method 8260B VOCs 1,1-dichloroethene (1,1-DCE), cis-1,2-dichloroethene (cis-1,2-DCE), trans-1,2- dichloroethene, tetrachloroethene (PCE), trichloroethene (TCE), and vinyl chloride (VC). On-post monitoring wells were sampled for the SW-846 Method 6010/6020 metals lead, cadmium and nickel. Additional samples were collected off-post from the wells with GAC filtration systems. Samples were analyzed by either Test America in Arvada, Colorado, or APPL in Fresno, California. Parsons’ chemists validated and verified the data in accordance with the CSSA Quality Assurance Program Plan (QAPP). All detected concentrations of VOCs and metals are presented in Attachment 4.

December 2007 Sampling

Laboratory results for the December 2007 event were not included with the Period 31 Progress Report submitted in January 2008 because they were not yet available. The results are included in Attachment 4. The action level (AL) or applicable maximum contaminant level (MCL) was exceeded in on-post wells CS-9, CS-11, and CS-MW25-LGR for the analytes lead and/or chromium. No on-post monitoring wells exceeded the MCL for VOCs in December



2007. The MCL was exceeded in off-post well RFR-10 for PCE and TCE; however, this well has been equipped with a GAC filtration system since 2001.

March 2008 Sampling

Twenty-two on-post monitoring wells and the LGR zones of the four southern Westbay-equipped wells were sampled in March 2008. Off-post wells sampled in March 2008 included 29 private and public off-post drinking water wells with six post-GAC samples. Three off-post wells could not be sampled (JW-12, I10-5, and JW-26). JW-12 and I10-5 could not be sampled due to the inability to contact the well owners to confirm property access. The well owner of JW-26 has declined to participate in the groundwater program because they are selling their house in the future.

In March 2008 well CS-MW22-LGR had detections of lead at a concentration of 40 µg/L which exceeded the drinking water AL of 15 micrograms per liter (µg/L). No other on-post well had concentrations of lead above the AL or MCL in March 2008.

VOC MCLs were exceeded in on-post monitoring wells CS-D, CS-MW1-LGR, CS-MW16-LGR, and CS-MW16-CC for the analytes PCE, TCE, and/or cis-1,2-DCE. Westbay-equipped wells CS-WB01, CS-WB02, CS-WB03, and CS-WB04 had exceedances of either PCE and/or TCE in various intervals. No MCL exceedances were reported in any of the off-post wells. Post-GAC samples were collected in March 2008 and all samples were non detect for VOCs indicating the GAC units are functioning properly. On January 25, 2008 routine six month maintenance was performed on the GAC treatment systems installed at LS-6, LS-7, OFR-3, RFR-10, and RFR-11. The carbon canisters were exchanged and the ultraviolet lights were replaced.

June 2008 Sampling

Ten on-post wells were sampled in June 2008. Off-post wells sampled in June 2008 included 28 private and public off-post drinking water wells. Sampling was conducted between June 2 and June 26st, 2008. Laboratory results will be received in July 2008 and summarized in the next progress report.

On-Post GAC Systems

CSSA operated and maintained the permitted on-post GAC unit at Outfall 002 and the permitted discharge at Outfall 004 this period. A Discharge Monitoring Report is submitted each month the system operates to comply with Texas Pollution Discharge Elimination System permit requirements. No discharge occurred at either outfall this period.

Off-Post GAC Systems

Based on sampling results received in 2001 and 2002 indicating VOC levels above or approaching the MCL, GAC filtration systems were installed at seven off-post wells. In accordance with the CSSA Off-Post Monitoring Program Response Plan dated June 2002 and the Groundwater Monitoring DQOs, the off-post GAC filtration systems are maintained by CSSA



and sampled every six months. Monthly O&M activities for the off-post residential GAC filtration systems were performed this period. Work included inspection and replacement, as needed, of the pre- and post-GAC filters at wells LS-6, LS-7, RFR-10, RFR-11, and OFR-3. Confirmation samples from systems installed at wells LS-6, LS-7, OFR-3, RFR-10 and RFR-11 were collected in March 2008. Carbon canister exchange was completed in January 2008 for the off-post GAC systems. All results for the post-GAC water samples were non-detect.

Data Validation and Verification

Laboratory results from sampling efforts and investigations are validated and verified by Parsons’ chemists to ensure results are in compliance with CSSA QAPP requirements. Data validation and verification continued during Period 32 under CSSA projects TO 0008, DY01-Parsons, DY02-Parsons and Hankins & Anderson (H&A) Parsons. Parsons chemists conducted data validation for 57 data packages during Period 32 including:

• Four related to TO0008 sampling activities;

• Four related to DY01-Parsons sampling activities;

• Forty related to DY02-Parsons sampling activities;

• Six related to quarterly groundwater monitoring activities on DY02-Parsons; and

• Three related to environmental program activities on H&A-Parsons.

TO0008 data packages included sampling events for the six newly installed LGR monitoring wells. DY01-Parsons data packages included sampling events for the SWMU and AOC investigations conducted. DY02-Parsons data packages covered sampling conducted for the bioreactor treatability study and quarterly groundwater monitoring. H&A-Parsons sampling conducted included waste characterization and miscellaneous sampling required for the environmental program. Data packages were validated and verified in accordance with specific project DQOs and the CSSA QAPP.

Well Installations and Conceptual Site Model Update

As a result of data gaps identified in the Long-Term Monitoring Optimization (LTMO) study, six LGR monitoring wells were installed to further delineate plume extent and groundwater flow direction in spring 2007. Well locations are shown in Attachment 1. A draft report detailing the well installations was submitted December 2007. Comments have been received, and a final report is being prepared. Several rounds of groundwater sampling events have been accomplished at the new wells (CS-MW20-LGR through CS-MW25-LGR) since the installation, and the results are being incorporated into the basewide hydrogeologic conceptual site model (HCSM). The HCSM report is being updated to incorporate the data from the new monitoring wells, and update all site data through the December 2007 groundwater monitoring event.

PCE detections above the MCL occurred in the new LGR monitoring well CS-MW20-LGR at concentrations ranging from 1.6 μg/L to 1.8 μg/L. No PCE has been detected in the remaining five new wells. However, detections of inorganics above the appropriate comparison



criteria have occurred within two wells, CS-MW22-LGR and CS-MW25-LGR. Repeatable concentrations of lead above the action level of 0.015 mg/L have been reported in both wells, with the highest concentration being 0.091 mg/L (CS-MW25- LGR). In addition, zinc has been reported at CS-MW22-LGR at a concentration of 8.0 mg/L, which also exceeds the federal MCL (5.0 mg/L). Both of these wells are physically located near potential inorganic sources that have been documented by prior investigations such as Demo Dud near CS-MW22-LGR and SWMU B-8 near CS-MW25-LGR.

The HCSM update will also include data from extreme drought conditions (2006) to above-normal precipitation (2007). Of hydraulic interest, there has always been a groundwater “mounding” effect that has been measured at CS-MW4-LGR along Salado Creek in the central portion of the facility. Between March 2005 and December 2006, the aquifer had declined by more than 225 feet. By mid-2006 the persistent groundwater mounding effect along Salado Creek had dissipated, and for the first time since 2001, the groundwater surface was not dominated by the effect around Salado Creek. In 2007, central Texas received an abnormally high amount of rain from which the aquifer rebounded by more than 200 feet by September 2007. By March of that year the mounding effect reoccurred and the groundwater surface returned to its normal flow pattern.

Part of the intent of the new wells was to investigate the occurrence of this groundwater mound by placing wells at select locations around and near Salado Creek. Wells CS-MW20-LGR, CS-MW21-LGR, and CS-MW22-LGR have helped define the extent of mounding to the south. While the feature is still a predominant characteristic, it is somewhat diminished from prior years. The HCSM report will recommend tracer studies for future work to help quantify flow direction and velocity within the aquifer.

Treatability Studies

The Treatability Study subtask makes up approximately 10 percent of the RFI phase. As of the end of Period 32, this task is approximately 46 percent complete.

SWMU B-3 Bioreactor Treatability Study

SWMU B-3 Bioreactor Performance Status Reports were submitted to CSSA, TCEQ and USEPA on a monthly basis during Period 32. Approximately 6,500,000 gallons of groundwater extracted from CS-MW16-LGR and CS-MW16-CC have been injected into bioreactor trench 1 since the start of injection. Monthly Underground Injection Control (UIC) reports for the period, in accordance with CSSA’s Class V Aquifer Remediation Injection Well Permit, TCEQ Authorization No. 5X2600431; WWC12002216 were submitted to the TCEQ during period 32 on January 10, 2008, February 21, 2008, April 4, 2008, April 21, 2008, May 9, 2008 and June 10, 2008.

Groundwater samples were collected from sumps, wells, and/or Westbay-equipped wells after the discharge of the bioreactor delivery pump and prior to injection of the groundwater into SWMU B-3 trench 1. Sampling frequency was based on permit requirements and water availability. In general, injected groundwater samples are collected twice monthly and monitoring samples from the Westbay-equipped monitoring wells and injection trench sumps are



collected monthly. All samples were analyzed for permit parameters - VOCs and total dissolved solids as well as performance parameters by APPL, DHL Laboratory, and Microseeps Laboratory. Field data collected included injection volumes, injection pressures and the pH of recovered groundwater for TCEQ permit compliance. Analytical data collected for performance parameters include;

- Dissolved Organic Carbon - Methane, Ethane, Ethene - Hydrogen - Temperature, pH, specific conductivity - Oxidation Reduction Potential - Dissolved Oxygen - Total organic carbon - Carbon Dioxide - Hydrogen Sulfide - Alkalinity - Nitrogen, Nitrate + Nitrite - Additional ions including Sulfate, Chloride, Ferrous Iron, Manganese - Dehalococcides populations, and - Isotopic ratio analyses.

During period 32 (January through June 2008), rainfall has been minimal at the bioreactor site. The bioreactor is kept at saturated conditions by continually supplying supplemental water. Provisions are being made to supply supplemental water to the bioreactor as drought conditions are expected to continue. Trench 1 was bioaugmented with DHC in February 2008.

Monitoring results indicate that a significant amount of VOC components remain in the SWMU B-3 formation including cis-1,2-DCE (a product of reductive dechlorination of highly chlorinated species such as PCE and TCE), and minor amounts of fuel components such as toluene. Results also indicate that reduction dechlorination is on-going at the site. Degradation products, vinyl chloride and ethene, were present within the bioreactor and ethene was detected in Westbay-equipped well CS-WB05 and B3-MW01 during the period monitoring events. Ethene represents one of the final degradation products of attenuated chlorinated solvents. Other observations include:

• Water quality field measurements from the bioreactor sumps generally indicate that dissolved oxygen remains low (< 0.5 mg/L), oxidation reduction potential averages less than -180 millivolts, pH is approximately 6.5, temperatures ranges from 25 degrees Celsius (oC) to 34oC, and specific conductivity ranges from 0.69 to 3.52 millisiemens per centimeter. This data indicates the water within the bioreactor supports reductive dechlorination of chlorinated aliphatic hydrocarbons (CAH) by Dehalococcoides bacterium.

• The dissolved hydrogen concentrations within the bioreactor sump samples were in the range consistent with reductive dechlorination of CAHs by Dehalococcoides bacteria.



• Saturated conditions are being maintained within bioreactor Trench 1 with an average water thickness for the quarter of approximately 6.6 feet.

• Isotopic ratio sample results for Carbon indicate that there apparently remains an untreated source (enrichment of C12/C13 ratio) of TCE near CS-WB08 and Trench 6.

AOC-65 SVE System

Rehabilitation and expansion of the AOC-65 SVE system was completed in Period 31. The permit-by-rule (PBR) for the SVE systems was submitted to the TCEQ on January 08, 2008 and the system re-started in April 2008. Initial monitoring of the AOC-65 SVE system was accomplished April 14, 2008. Monitoring results indicate no exceedances of PBR limits occurred for the SVE system. The system is expected to operate periodically in Period 33, while blower shut-down problem is investigated and remedied. The SVE Operation and Monitoring/Maintenance Plan has been drafted and is currently under review.

PROJECTED WORK FOR THE NEXT PERIOD

Fact Sheets

Fact Sheets covering the 2007 groundwater monitoring were distributed to the CSSA mailing list. The CSSA mailing list was updated to include current addresses as residents moved into and out of the area.

Groundwater Monitoring

Continued sampling of on and off-post monitoring and water supply wells will continue in September and December 2008. The 2007 annual groundwater monitoring report will be submitted next period. The O&M at the residential GAC filtration systems (LS-6, LS-7, OFR-3, RFR-10, and RFR-11) will be conducted every three weeks during Period 32.

AOC-65 SVE System Operations

AOC-65 SVE system O&M will continue in Period 33. The system includes four blowers operating continuously, and O&M of those systems will be performed in accordance with the Updated O&M Manual for SVE Systems at CSSA. Monitoring is expected to occur twice monthly, monthly, and semi-annually.

SWMU and AOC Investigations

Investigations, interim removal actions, and/or reporting will be continued for SWMUs B-2, B-8, B-20/21, B-24, I-1, B-71, AOC-63, AOC-64, AOC-67, AOC-68, AOC-69, and AOC-73. Reports summarizing investigation results will be submitted. An ecological risk assessment will be completed after all investigations of units in North Pasture are completed.
